I just came back from Thanksgiving with family in the Philadelphia area. My SIL and I are both gardeners and she took me to see Ott's nursery on Friday. It is somewhere near Skippack. I was completely blown away. I just had to buy some plants and struggle to get them back on the plane--not sure how they liked being X-rayed! Anyway, it was the most amazing greenhouse for gardeners and today I tried to find a website but couldn't. Does anyone know if they have one and what it is?
